How can i graph this equation by plug in numbers????
x^2-y^2=9

HELP PLZ!!!!!!THX ALOT!!!!

Assign numbers to x and solve for y then put them in a graph:
let's say x is -3

Then 9=y^2+9
y^2=0
y=0

Ok now x= -4

16=y^2+9
y^2=5
y=2.236

Also you can assign y a number and solve for x
Say y=0
Then x^2-0=9
x=3
